Patent TW-369752-B (TW)
Title: System and method of detecting and preventing fraudulent telephone calls in a radio telecommunications network
Inventor: FOTI GEORGE
IPC: H04W12/12
Filed: 1997-10-24
Granted: 1999-09-11
Abstract: A system and method for detecting a fraudulent call origination in radio telecommunications network having a subscriber's home location register (HLR) for storing a stored location for a mobile station, a serving mobile switching center (MSC) in which the call origination is initiated, and a MSC-Location (MSC-L) covering the location for the mobile station stored in the home HLR. The serving MSC sends a reporting message to the home HLR when a call is originated from the mobile station in the serving MSC. The reporting message indicates a reported location for the mobile station. The home HLR then sends paging request messages to the serving MSC and the MSC-L requesting the serving MSC to page the mobile station in the reported location and requesting the MSC-L pages the mobile station and sends a paging result to the home HLR. The home HLR compares the stored location to the reported location, and analyzes the locations and the paging results to determine whether the call origination is fraudulent. If the call origination is determined to be fraudulent, the call is disconnected, and the mobile station is barred from originating calls until a proper personal identification number (PIN) code is entered.

In dependence on the quality a new determination of the medium field strengths of each frequency is postponed in terms of time, for being able to react on changes faster or slower. By selecting the values for good quality, interferences with the superimposed system are obtained. A device and a method are provided, which are flexible, involve only low interferences and disturbances and which are easy to implement.

Title: A method for scaling an image
Inventor: ONG JOON-SUAN
IPC: G09G5/39
Filed: 1998-06-08
Granted: 2000-03-21
Abstract: A method for scaling a portion of an image shown on the display of a PDA is disclosed. After scaling, the display of the PDA switches to show the scaled view of the portion of the image. This method essentially involves the scaling of a first set of display information which forms the portion of the image, into a second set of display information which makes up the scaled view. During the scaling process, a series of look-up tables containing display conversion information are generated. An address-indexing technique is then used with the look-up tables to achieve an efficient and fast scaling process. The method also employs a smoothing technique to provide a more pleasing scaled view.

Title: Pneumatic scraping tool
Inventor: HARTMAN ROBERT L
IPC: B25D9/06
Filed: 1998-06-30
Granted: 2001-01-01
Abstract: A pneumatic scraping tool includes a pneumatic hammer assembly including a cylinder in which a piston reciprocates for repeated impact against an anvil or blade holder which is rotatably received within an end of the cylinder and carries a scraping blade. The anvil has an annular flange which stops its insertion in the cylinder, and is retained in place by a nut threadedly engaged with the cylinder and having an end wall spaced from the cylinder end a distance slightly greater than the flange thickness to permit reciprocation of the anvil. Exhaust air passes along a groove in the outer surface of the cylinder to an annular chamber in the nut and thence through four exhaust ports exiting at the end wall of the nut. A plug portion of the anvil projects through a central opening in the nut end wall and is received into a socket in a blade housing. Blade fingers project laterally into the socket. Alternating side grooves and flats on the plug portion allow the blade assembly to be rotated roughly one-quarter turn between a latched condition and a release condition in which the plug portion can be inserted into and removed from the socket. A spring-biased detent ball in the cylinder engages a square inner end of the anvil to form a ratchet, accommodating rotation of the anvil in only one direction.

Title: Layered resist system using tunable amorphous carbon film as a bottom layer and methods of fabrication thereof
Inventor: BABICH KATHERINA E
IPC: G03F7/11
Filed: 1998-08-24
Granted: 2001-12-11
Abstract: Disclosed is vapor deposited thick are layer and method of preparing single and tunable thick bottom layer coatings based on amorphous carbon films. These films can be hydrogenated fluorinated nitrogenated carbon films. Such films have the index of refraction and the extinction coefficient tunable from about 1.4 to about 2.1 and from about 0.1 to about 0.6 respectively at UV and DUV wavelenghts, in particular 365, 248 and 193 nm. This makes the films extremely useful to be used as thick bottom layers in a bilayer resist system. Moreover, the films produced by the present invention can be deposited over device topography with high conformality, and they are etchable by oxygen and/or fluorine ion etch process. Because of these unique properties, these films can be used to form a single or tunable thick bottom layer at UV and DUV wavelenghts to produce practically zero reflections at the resist/bottom layer interface. This greatly improves performances of semiconductors chips.
